Title:
  Profiles that require duplex audio like Head Set (HSP) and Hands Free
  (HFP) do not work on machines with Broadcom BCM20702A0 Bluetooth chips

Status in HWE Next Project:
  Fix Released
Status in bluez package in Ubuntu:
  Fix Released

Bug description:
  This problem seems to occur on every device that uses  the BCM20702A0
  Bluetooth hardware.

  How to reproduce:

  (1) Pair a bluetooth headset with a machine equipped with a BCM20702A0.
  (2) Activate the device.  Usually there is a button on the headset you should press to notify the bluetooth stack that you're ready to use the device.  This creates SCO link and the plumbs the audio components.
  (3) Open the sound settings tool and select the bluetooth device under the "Input" and "Output" tabs.  Under each tab you should see a table with an entry that has a headset icon on the left with the bluetooth device name to the right.  This is the item to select.

  Now, everything should be configured so that you can use your
  bluetooth device to hear and record audio.  Test this by:

  Testing Input:

  (1) In the sound settings tool, select the "Input" tab.
  (2) Make sure the "Input Volume" is not muted and the scale widget is not set to zero.
  (3) Make sounds into the headset mic -- you should see the "Input Level" bar raise.

  Testing Output:
  In the same program:
  (1) Select the "Hardware" tab.
  (2) In the box labeled "Choose a device to configure", select your bluetooth device.
  (3) A combobox should appear at the bottom of the window labeled "Settings for the selected device".  Choose "Telephony Duplex (HSP/HFP)".
  (4) Now click on the "Test Speakers" button to the right.
  (5) Run speaker test.  You should hear a sound.
